SNAP-HOOK.

To all whom it may concern.

Be it known that I, ALBERT LEON STROHL, a citizen of the United States,and a resident of Hardin, in the county of Ray and State of Missouri,have invented certain new and useful Improvements in Snap Hooks, ofwhich the following is a specification.

My invention relates to harness snaphooks, and has for its object theprovision of a hook that is reasonable in cost of manufacture, moredurable than the snaps of ordinary construction, and so constructed thatthe hook portion is of double strength, being formed of two overlappingunits that interlock when in a locked position. Furthermore the hook iseasily operated and impossible to unlock when in position except whenproperly manipulated.

The construction and operation of my improved snap-hook will bedescribed hereinafter and illustrated in the accompanying drawing, inwhich- Figure 1 is a top plan View of my improved snap-hook showing itin a closed position in full lines and in an open position in brokenlines; Fig. 2, a side view; Fig. 3, a fragmental View of the hookextended from base 1; and Fig. 4, a cross-section of the base andcasing.

In the drawings similar reference characters indicate correspondingparts in the several views.

The base 1 of my improved snap-hook has an eye 2 at one end, to whichmay be secured the harness-strap (not shown), and at its other end ahook 3, with a flange 1 project ing from one edge. The other member ofthe hook consists of a casing 5, having flanges 6 that engage base-plate1, and is formed with a hook 7 at one end complementary to the hook 3,and when in operative position engages its outer portion.

The base-plate 1 and casing 2 are pivotally secured together by means ofrivet 8, secured to base 1, and engaging a hole 8 in casing 5, or othersuitable fastening, and the two hooks are held normally in engagementwith one another by means of a spring 9, secured at one end to pin 10 onthe base-plate 1, bent around rivet 8, as shown at 11, and engaging oneof the flanges 6 on casing 5, said flanges being shown formed by cuttingthe casing on three sides and bending it inwardly; but it will beapparent that the flanges may be formed in any other manner withoutdeparting from the spirit of my invention.

Specification of Letters Patent.

Application filed February 15, 1909.

Patented Sept. 28, 1909. Serial No. 477,847.

12 indicates a flange or projection on the edge of base-plate 1 thatengages the flange 6 on the casing 5 to stop the casing when movingunder the impulse of spring 9 when the hooks 3 and 7 are in a lockedposition, flange 4 on hook 3 also serving the same purpose, as well asto strengthen said hook.

13 indicates a lug on the outer side of base 1, and 14 another lug onthe other side of casing 5, said lugs forming finger-holds formanipulating the hook in swinging the two hooks 3 and 7 apart againstthe resistance of spring 9, and are shown constructed by cutting themetal of base 1 and casing 5 on three sides and bending the tongueformed thereby outwardly, but said lugs may be formed in any othermanner, the construction shown not being essential to the completeoperation of my invention.

It will be understood that when the hooks 3 and 7 are swung apart, asshown in Fig. 1, they are in position to be attached to a ring or loopon the harness or other device, when by releasing the pressure on thetwo parts the spring 9 will swing the two hooks into engagement and theywill securely hold the ring or loop from displacement, and as the hooks8 and 7 overlap one another the device is very strong and will bear agreat strain without breaking.

Having thus described my invention, what I claim is.

A snap-hook consisting of a base-plate having a hook at one end with anoutwardlyextending flange, the other end of the base plate having astrap-loop thereon, a spring secured to said base plate, a casingpivotally secured to said base and having flanges engaging it, saidspring engaging one of the flanges on said casing, a hook formed on saidcasing and normally engaging the first-men tioned hook, the flange onthe first-mentioned hook forming a stop to limit the movement of thehook on the casing, a lug on the base plate engaging the flange on thecasing when the hooks are in engagement, and finger-hold lugs extendingoutwardly from the base plate and casing, substantially as shown anddescribed.

In witness whereof I have hereunto set my hand in presence of twosubscribing witnesses.
